The Legatia Pro drivers are high-performance midrange, and the plastic mounting baffles that 
come from the factory in virtually every vehicle will lead to buzzes, rattles, vibrations, and 
resonances, all of which negatively affect the Legatia Pro installation. In other vehicles, you may 
have attached the Legatia Pro midrange’s directly to the door metal (hopefully with a layer or two 
of self-adhesive sound damping in between), but this is still not entirely ideal. In whatever scenario 
you have installed your Legatia Pro midrange, there are certain “tricks” and techniques that may 
be applied to get the most out of your Legatia Pro component set, specifically the midrange 
installation, as follows:

Mounting the baffle, sound damping, and “decoupling” 

The mounting baffle or mounting location should either be secured extremely well to the vehicle’s 
body, or completely isolated from the vehicle’s chassis. The reasoning is that the speaker baffle 
panel will vibrate and will radiate sound. Even small vibrations can result in the baffle itself 
radiating more sound than the actual speaker at certain frequencies. The mounting baffle or 
mounting location should be damped with a layer of typical sound damping to reduce the Q of 
the baffle and lower its vibration resonance frequency below the range of the driver’s frequency 
response. In many cases, using thicker baffle panel in concert with self-adhesive sound damping 
can also be advantageous, provided the rearward wave of the speaker has no obstructions created 
by the baffle itself.  Finally, if possible, the speaker should be mechanically decoupled from the 
baffle. This can be something as simple as a layer of self-adhesive foam tape, to more exotic 
examples of decoupling, including rubberized rings or multiple-layer septum shielding.

Building solid mounting baffles 

In many cases, it is advisable to mount your Legatia Pro midrange’s in high-stiffness wood or 
high-density fiberglass (or wood treated with fiberglass resin). Hybrid Audio Technologies 
recommends the use of a solid hardwood, such as birch or oak, namely because these woods are 
stiff and help to dissipate resonance, and screws can be inserted and removed multiple times 
without stripping. Avoid Medium Density Fiberboard (MDF), particularly in wet environments 
like the door, as the MDF will act like a sponge with humidity and moisture, and not only that, the 
MDF is a dense, but not stiff type of wood, and the results may not be particularly noticeable if 
you use MDF. Once your baffle is built, it must be covered in one or two layers of a good-quality, 
brand name self-adhesive damping product; a solid wood mounting baffle with sound damping 
treatment will augment the Legatia Pro installation by eliminating resonances.

Lesson Four: Point-Sourcing

The term “point-sourcing” is often used to describe the technique of having a single pair of 
speakers in an installation cover the majority of the critical middle band frequencies. In many 
installation scenarios, the Legatia Pro midrange could be considered a point-source speaker driver, 
because it has the ability to reproduce up to six octaves of tones. Point-sourcing, if done correctly, 
can lend itself to a variety of valuable attributes, including precise image definition and stable 
sound staging character. By applying Lessons 1-3 above, the Legatia Pro midrange can be used as a 
point-source driver to achieve excellent staging and imaging results.

The lesson to be learned here is that the Legatia Pro midrange, given its wide-bandwidth design, 
can faithfully reproduce as much as six octaves of tones, and would make a valuable addition to 
any sound system as a point-source driver for the spectrum comprising vocal imaging cues.

Lesson Five: Reference

One of the most important things to do before completing your Legatia Pro installation is to get a 
reference for your future listening tests. To really know what a snare drum sounds like, you must go 
and listen to one, in person, live and un-amplified. There is no substitute for the visceral impact and 
emotion of live music. Nothing else in life can touch your soul the way music does. Whether it’s a 
200-member orchestra, or a four-piece fusion band, nothing compares to the phenomenon of live 
music.

Take this as Hybrid Audio’s official request: become a student of music and your mobile audio 
sound system will be better for it. We want nothing more than to know there are great sounding 
audio systems around the world using our products, and you’d make us all very proud if you 
became a student of music and learned its beauty and passion.

Mounting Baffle Considerations

Now that we have revealed five of our most important “Lessons Learned”, we can now apply these 
lessons to the Legatia Pro installation. The first important matter is the physical installation of your 
Legatia Pro midrange, and more specifically with respect to improving the Legatia Pro midrange’s 
mounting baffles. Most vehicles’ factory mounting locations for speakers are less than ideal. In 
most cases, the OEM speaker mounting flanges are likely nothing more than flimsy extruded 
plastic, and provide no sonic benefit to your Legatia Pro installation.
